Application filed October 27, 1916. Serial No. 128,033.

To all whomz't mag concern: f

Be it known that I, SAMUEL *FURMAN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Patch-Applying Mechanism inMachines for Making NVindow- Envelop Blanks, of which the following is aspecification accompanied by drawings forming a part of the same, inwhich Figure 1 represents a side view of so much of a machine for makingwindow envelop blanks as is necessary to illustrate the nature andoperation of my present invention with one side of the frame removed forthe purpose of clearness.

Fig. 2 is an end view of the same looking from the left.

Similar reference figures refer to similar parts in the difierent views.

My present invention relates to that portion of the mechanism of awindow envelop making machine which is directly concerned in applyingthe patch to an opening in the body of an envelop blank.

The mechanism embodying my present invention is designed to 'be operatedin connection with the window cutting and gumming mechanisms of amachine for making window envelop blanks, on which Letters Patent of theUnited States No. 1,182,364

' was granted to me May 9th, 1916.

The envelop blank when presented to the mechanism for applying thepatch, has an opening formed therein, and gum applied to the margin ofsaid opening and is ready to receive a transparent patch to cover saidopening.

Referring more particularly to the parts;

1 are the side frames of the machine in which all of the shafts arejournaled.

2 is a shaft to which the patch carrier 3is fastened and also thestationary cams 4' are loosely fitted on said shaft.

5 is the shaft of the blank bed .5? and the lower ends of forks 6'areloosely fitted on said shaft. The upper ends of said forks are fastenedto cams 4 thereby preventing said cams from turning on shaft 2.

7 is a bar connected to patch carrier 3 and radially slidable therein.Each end of said bar extends some distance out of said carrier er s id sionary a s Ant Specificacion of Letters Batent.

on MAKING WINDOW-ENVELOP Patented. Oct. 7, 1919.

"friction rollers 8 are fitted on each end of "said bar and in contactwith stationary cams 4. v y

. ,9' are pins" mounted on the slidable bar 7 and sliding therewith inthe body of the patch carrier 3.

The cams 4 are designed of such a shape as to move said bar to and fromthe center of rotation of said carrier thereby moving said pins 9, whichare connected to the said bar, out of said carrier when in contact withsegments or rollers 10, to meet and enter the openings 10* in saidsegments or rollers for the purpose of engaging a patch thereon andrecede into said carrier 3 when coming in contact with the blank bed 5thereby releasing said patch and applying it to a margin of the openingin the envelop blank.

11 are springs. One end of each spring is fastened to sliding bar 7 andthe other ends to the shaft 2 thus tending to keep cam rollers 8 whichare on sliding bar 7 in contact with stationary cams 4, so as totransmit the sliding motion to said pins 9 in said carrier 3.

12 is the roll of transparent paper, the

- free ends of which is fed into the machine by means of roller 13 onshaft 14, and the roller 15 the ends of which are journaled in'frame 1.Any suitable mechanism, not shown, can be employed for operating thefeed rollers 14 and 15 intermittently to feed the patches singly uponthe patch support 18 in proper time to be transferred by the segments 10to the patch carrier 3.

16 is a stationary knife and 17 is the movable knife for cutting patchesof a proper width from the web which is fed y the rolls 13 and 15.

18 is a supporting table for said patches to rest on preliminary totheir being engaged by the slidable pins 9.

' The various rollers and the patch carrier tion. as indicated by thearrow. 1

Having thus described my invention, I claim and desire to secure byLetters Patent:

1. In a patch applying mechanism of an envelop machine, a framework, arotatable shaft'journaled thereon, a patch carrying roll on said hafcams held.- ocse y a d- 3 are driven by means of gears in the direcshaftat each end of said patch carrying roll, means for holding said camsfrom rotation, a bar radially movable in said patch carrying roll andprojecting beyond its ends, rolls journaled on the ends of said bar incontact With said cams, and means carried by said bar for engaging apatch.

2. In a patch applying mechanism of an envelop machine, a framework, arotatable shaft journaled therein, a patch carrying roll held on saidshaft, means carried by said patch carrying roll for engaging a patch,means for actuating said patch engaging means to engage a patch,comprising cams held loosely on" said shaft at each end of the patchcarrying roll, means for h0ld ing said cams from rotation, and a bedroll running in contact with said patch carrying roll for applyingpressure to the patch as it is carried between said rolls, and means forreversing said patch engaging means to release the patch.
